T


he first of two OCC lines, each with a capacity of 1,000 bdtm/d, supplied by


Andritz to Wamat Paper in the Shandong province of China, has been successfully started up. Start-up of the second OCC line is scheduled for the end of this year. Both lines produce pulp for corrugated medium as the final product. Andritz delivered all of the equipment, from pulping to headbox screening, including a disc filter for fibre recovery. The lines feature: ● A low-consistency pulping system, including a FibreSolve FSR pulper with flow-optimised rotor and vat for low power consumption, as well as a FibreGuard detrashing system with a FibreWash Drum that


fractionators are equipped with PrimeRotors to ensure efficient reduction of stickies and debris. ● A novel system also uses a smaller number of pumps, resulting in significant reductions in energy consumption. General manager at

Clothing for start-up of Oulu Mill’s BM7 line supplied by Valmet


Start-up clothing is being supplied by Valmet for Stora Enso’s Oulu Mill in Finland. The order includes forming


fabrics, press felts, shoe press belts and dryer fabrics for use on the PM7 grade conversion by Valmet, which will be starting up towards the end of 2020. “Valmet has been our main clothing supplier in Oulu for a long time,” says Janne


Myllykangas, area manager BM7 and deputy project director at Stora Enso. “We are pleased to continue working together in this strategic project, too, as the performance of the fabrics and felts is crucial for end product quality and production efficiency. We have set high requirements for the technical support at the start-up and during optimization. We trust


that Valmet can meet our expectations.” Martti Heinola, director for paper machine clothing at Valmet, commented: “We are happy that Stora Enso has chosen our clothing for the start-up of BM7. All in all, the order includes 50 per cent of the forming fabrics and press felts, and 100 per cent of the dryer fabrics for the first two years with an option for the


third year. “Valmet Black Belt shoe press belts were already included in Stora Enso’s earlier order for this project.
